摘要
高压空冷器制造工艺技术难关之一就是实现管子与管板间的深孔加丝全位置脉冲自动钨极氩弧焊接 ,通过攻关试验 ,研制了国内第一台深孔加丝管头专用焊机 ,同时总结了其焊接工艺和焊接技术 。
The main technical difficulty for fabrication of high pressure air cooler is to realize the pulse TIG automatic welding for all welding position between the pipe and tubesheet with deep holes. Our plant made the test and fabricated the first special welding equipment for the tube head of deep holes in China, in the mean time, we also summarized the welding processes and solved the difficult problem for welding of tube head and its post welding heat treatment.
